Welcome to the "Learning Ergonomics" video series. Repetitive strain injuries are a serious concern in the modern workplace, and this series will explore the causes and prevention of RSI through the study of position and movement. When it comes to ergonomics and avoiding RSI, one of the most important things at work is your chair. It can put you in the right position, or it can contribute to unnecessary strain. This is the third video lesson out of seven, and it will share what to look for, what to avoid, and what to fix. Don’t take potential work injury sitting down! Remember, a healthy workplace is a productive workplace!
